Economy / Service Announcements / Re: Introducing XCoinCall - start calling with Bitcoins

I compared your prices with the ones I have from my mobile provider. Calls with xcoincall compared to my Swedish cellphone. | Germany | xcoincall is cheaper | 30% of mobile rate | | Switzerland | xcoincall is more expensive | 500% of mobile rate | | USA | xcoincall is cheaper | 30% of mobile rate | | UK | xcoincall is cheaper | 90% of mobile rate | | Sweden (different mobile provider network) | xcoincall is cheaper | 39% of mobile rate |
These are actually very good prices, I might try it out when I need to call an expensive call next time. I don't like the PM spam though. |

I noticed a small bug; when scanning a qr code for sending with amount=0.0892, the amount sent was exactly 0.089, so it seems amounts gets rounded somehow.
(Wrote this here since apparently Google now requires google+ for commenting in play store).
Thanks for the report. I am unable to reproduce this. I have made a payment request and sent it to myself in an email like this: Tap Receive -> tap the keyboard icon -> enter 0.0892 -> Ok -> Share Payment Request -> Gmail -> my email address Result: bitcoin:1BoBsT2QicxGf3eroqcaXTwz9qaYiZZSNC?amount=0.0892I have turned the string into a QR-code: http://imgur.com/KJnqj3HWhen I scan it I get the correct amount 0.0892 Here is the transaction i sent: https://blockchain.info/tx/51096ef74647dd692b2bb64c88f0b9ff1b87fc231daf1ba3533ed771f9ae5043If you can reproduce the bug please send me a copy of the QR code you scanned. I noticed a small bug; when scanning a qr code for sending with amount=0.0892, the amount sent was exactly 0.089, so it seems amounts gets rounded somehow.
Which app was the QR code created with, Mycelium, or something else? Hmm i paid something on a website, but I can't remember what it was. I had the qr code in my qrdroid history though. The qr code text in history is: bitcoin:1GTWuwvEMVLGSWCBgZcnBkBqS9AQER1RF?amount=0.0892..I guess that is according to the the standard. Look at that address and you'll see both the original transaction from the qr code and the 0.0002 top up I had to make. Edit: The qr code was from chunkhost.com |

Hej, Jag har sett artiklar som dessa senaste dagarna: http://www.bloomberg.com/news/2014-01-21/bitcoin-becomes-art-as-swedish-taxman-rejects-creative-currency.htmlOch undrar vad det innebär i praktiken. Min tolkning är så... Om man har bitcoins som man säljer och får svenska kronor, så beskattas detta som inkomst. Dvs beskattas ganska mycket. Jaja, jag har nog inte tänkt sälja mina bitcoins iallafall, utan försöker stanna inom bitcoinekonomin. Så om man stannar i bitcoinekonomin, är det skattefritt då? Dvs, om jag utför en tjänst åt någon, och denne betalar mig en bitcoin, så beskattas inte det (såvida jag inte säljer bitcoinen och får svenska kronor, men det gör jag inte). Sedan utför någon en tjänst åt mig, och då ger jag denne bitcoinen från den tidigare transaktionen som betalning. Inte heller då sker det någon beskattning, för det är inte "pengar" som bytt ägare. Alltså kan man leva skattefritt om man kan lyckas leva sitt liv inom bitcoinekonomin. Nice, hoppas det kommer fler ställen som accepterar bitcoins snart... Kan någon bekräfta eller dementera dessa vilda spekulationer? Enligt det jag hört från Skatteverket när jag ringt och frågat så beskattas vinst på bitcoin som inkomst av kapital (30% rakt av). Vinsten beräknas på kursen som anges på de kvitton på affärer du bör kunna visa upp, dvs. inte någon kurs från någon exchange någonstans. Man får inte dra av för förluster, och om man minat så räknas det som att man köpt dem för 0. Man får inte heller dra av för kostnader i samband med t.ex. mining. Ovanstående gäller för privatpersoner. Gällande att inte skatta om du bara handlar för bitcoin, så är det inte tillåtet men såklart möjligt, på samma sätt som med kontanter du fått utan att skatta. |

Ni killar måste ju vara rika idag! Läste om någon som ville köpa BTC för 8000kr här för över ett år sedan! Berätta gärna lite mer om hur det går idag  Att vara rik är ju relativt, lever du på mer än existensminimum så är du redan bland de 8% rikaste i världen... |

nonce in this case is different from lottery in that it can increment to cover the entire range (from 0 until overflow) so it's 100% sure to be able to find a match. It's like you buy every possible number in lottery. Say if the answer is distributed equally within 0 ~ 255, if you intentionally restrict your coverage within 0 ~ 58, then in (255-58)/255 = 77% of the time you can never find the answer.
No. That is completely wrong and confused. You are not 100% sure to find a match. Unless the hash function is broken, every attempt is unrelated— there could be 5 matches in a row, or a whole nonce range which doesn't match. When it fails, it just increments the extranonce or timestamp and carries on. At the current difficulty the probability of any value being a match is around one in seven hundred million. Puncturing the nonce space does not reduce your probability of success in the slightest. Unless you also hash for the nonces in between but discard the results.. which is of course stupid. Under the assumption that profit is the motive No, under the assumption that there is no benefit at all, including profit, of calculating hashes you will not publish. Unless he was testing the randomness of the algorithm, but I doubt it. OffT: Why don't we just ask this guy? http://citeseerx.ist.psu.edu/viewdoc/download?doi=10.1.1.45.1255&rep=rep1&type=pdf |

Bitcoin / Bitcoin Discussion / Re: Poll - Why are you generating BitCoins?

Was surprised that many have voted that they are not generating. So are they speculating or something else?
Note that the poll is from January 2010, bitcoin didn't yet have an exchange rate, some weren't even sure the system would work etc. Mining/generating made your computer slow, so getting only a few blocks every day wasn't really worth it for some. Fun fact is that I used term "generating" since "mining" wasn't invented yet :p |

Old thread bump...
I'm interested in how attitudes might have changed over the past few years, are we still all about creating a new idealistic global currency with privacy benefits or have we (de?)evolved into closet investors only interested in biding their time and hoping for the value of Bitcoin to rise?
Thoughts people?
When I created the poll I voted for the last alternative, this is still valid for me, but over the years I have gotten more interested in the potential benefits for the rest of the world than I was back then. |

I definitely wouldn't install that in my computer.
First of all, CPU/GPU mining is no longer profitable.
Secondly, a zip archive with a copy of the installed application folder of guiminer together with files named *.exe.exe? I haven't checked but this is most likely a trojan/virus.
